Phenomenon: What kind of light mountaineers have stumbled upon on Dinara?
Last weekend numerous mountaineers have visited Dalmatian mountains covered with thick snow layer. Among them were Ivan Zebić – Klepton from Mountaineering Society Dinarids from Split, and Jozo Vitić from Mountaineer Society Svilaja from Sinj.
In the afternoon two mountaineers went towards the mountain shelter “Rupe” on Dinara, at 1363 metres above the sea level. Night caught them on their way, and what should have been an usual winter climbing experience was disrupted by an extraordinary sight.
Some 50 metres away from the trail, the depression in the ground was visible, with approximate diameter 5 m and approx. depth 3 m. Such holes are normal part of Dalmatian mountain karts terrain, but this hole was special because the light was coming out of it.
Two mountaineers were convinced at first that someone set camp right in that hole and the light they see is from the fire or torch. But when they came closer they saw nothing but the snow.
Mountaineers had observed this phenomenon from 18:15 to 18:30.
“We were not able to explain what that was that we saw. The most logical answer would be that this hole for some reason can retain light of the day. As the time was passing the light was not fading. I captured this phenomenon with my camera but it has bad resolution and didn’t caught the real situation which was much more intense ‘in live’. And couple days after we captured it, we still talk about it.” said Ivan Zebić – Klepton, the eyewitness and the author of photographs.
We bring you the photos of this phenomenon, one of which was processed to enhance the contrast, and also more photos of the ascend on top of Dinara, on the snow higher than 3 metres.
